i w, are such as to have the main pattern-surface h continue in rotation, the pawl D4 will be kept fromengagement with the ratchet 45, and the auxiliary surface a will remain at rest.

The auxiliary pattern-surface will be moved more or less frequently, according to the requirements of the bars and the projections on some of them of the main patternsurface immediately below the nger w, a bar without a roll permitting the pawl D* to engage the ratchet-Wheel, as in Fig. l, Whereas as soon as a roll on abar meets the said ringer it is lifted, removing the pawl from the ratchet 45.

y l. The main pattern-surface, its shaft,tlie hub i, the toothed hub 6, gearing to move it positively7 and the auxiliary pattern-surface, and means to determine the time of the rotation ofthe main pattern-surface, combined with a ratchet connected with the auxiliary patternsurface, and with a Jawlcarrier, and with means to actuate it, to turn the auxiliary ratchet, and to raise and lower the said pawl to enable it to engage and turn the said ratchet with greater or less frequency, substantially as described. A

2. A positively-moved main pattern-surface, with its gearing and with means to move it or leave itat rest, combined with dan intermittently moved auxiliary pattern surface, its ratchet-wheel andpawl having its movements governed by the main pattern-surface, substantially as described.

3. The positively-moved hub 6 and the pawl D4, combined with the main patterireylinder and its connected toothedhub, and the auxiliary patternsurface and its ratehet-wheel, either of which may be moved by its corresponding hub or pawl, according to the indicators moving with the main pattern-surface, substantially as described.

4. The auxiliary pattern surface and the main pattern-surface' provided with gearing to positively move it, and also provided with a row of indicators or rolls to control the order of movement of the auxiliary patterirsurface,

'combined with a pawl and ratchet to move the HORACE VYMAN.
